RG6 Coaxial Cable: Installation Guide for CATV, Satellite & Security (2026)
Mar 21, 2026
RG6 coaxial remains the standard for cable television, satellite, and analog security camera systems. This guide covers cable selection, connector types, and signal loss management.
RG6 Cable Specifications
| Spec | Standard RG6 | Quad Shield |
|---|---|---|
| Impedance | 75 ohm | 75 ohm |
| Center conductor | 18 AWG CCS | 18 AWG CCS |
| Shielding | 60% braid + foil | Dual foil + dual braid 90%+ |
| Frequency | 5 MHz - 3 GHz | 5 MHz - 3 GHz |
| Loss @ 1GHz/100ft | ~5.6 dB | ~5.6 dB |
Always use quad-shield in commercial environments for EMI rejection.
Compression vs Crimp
Compression connectors are the professional standard — weatherproof, mechanically secure, and consistent. Crimp connectors are faster but prone to quality issues. For professional installations, compression is the only acceptable method.
Splitter Selection
Every 2-way split costs ~3.5 dB. A 4-way costs 7 dB. For systems with 4+ drops, use a distribution amplifier. For satellite, use 5-2150 MHz rated splitters.
Installation Tips
Maintain 6x cable diameter bend radius (~2.5 inches for RG6). Keep 12 inches minimum from AC power lines. Use UV-rated cable and weatherproof connectors for outdoor runs.
